Add a new macro wrapper WITNESS_CHECK() around the witness_warn() function.
The difference between WITNESS_CHECK() and WITNESS_WARN() is that
WITNESS_CHECK() should be used in the places that the return value of
witness_warn() is checked, whereas WITNESS_WARN() should be used in places
where the return value is ignored. Specifically, in a kernel without
WITNESS enabled, WITNESS_WARN() evaluates to an empty string where as
WITNESS_CHECK evaluates to 0. I also updated the one place that was
checking the return value of WITNESS_WARN() to use WITNESS_CHECK.
